This video presents shortly the process of machining of double layer prototype PCB, containing 144 pin LQFT & 32 pin QFP components. Each side of the prototype PCB (top & bottom layers) is processed in a completely automatic mode. Intervention of the operator is necessary only when the board should be flipped to process the bottom layer and make a fiducial registration.
In the clip is represented A636 – machine with large table, servo positioning system, automatic tool change (16 toolholders) and 60K rpm spindle.
The video shows the performance of the following programs and procedures: Insulation (Top Layer), Rubout (Top Layer), Drill (Top Layer), Fiducial Registration (Bottom Layer), Insulation (Bottom Layer), Rubout (Bottom Layer), Cut (Bottom Layer).
